Why do people post things, and when they get an answer they don't like, delete it? I'm sorry, but if you have a job interview, you wear dress clothes. If you're tired of seeing BFN's, stop testing so early. I do understand people get ahead of themselves with testing, but if you're testing at 7dpo, even if the egg was fertilized, it most likely hasn't even implanted yet. It just causes unnecessary sadness.
